The RDL ST-PD5U Switching Supply Distributor is the ideal choice where power distribution from a current-limited switching power supply is needed. It is suitable for powering up to five modules from a single power supply. The current limiting circuitry in many switching power supplies will cause the supply to shut down upon power-up when a high current capacitive load is connected. Upon application of power, the ST-PD5U ramps the voltage up, charging any load capacitance as quickly as possible, then switching full voltage to the load. If reverse polarity is connected to the input, the ST-PD5U disconnects the load until the condition is corrected.
In system design, various modules are frequently operated from a single power supply. Good engineering practice requires that the power wiring to each module originate at the power supply output. The ST-PD5U serves as the power source for each of five modules. A single ST-PD5U can provide power to RDL's floating modules. A separate ST-PD5U can provide power to ground-referenced modules.
Note: Do not intermix floating and ground-referenced modules from a single ST-PD5U.
Power and Fault LED indicators.
Input/Output Voltage of 24 VDC @ 2 A.
Soft start from switching supply.
Use the ST-PD5U combined with other RDL RACK-UP, STICK-ON, TX, or FLAT-PAK series products as part of a complete audio/video system.
